Many people looking into drug rehab in Harrisburg, Illinois may choose to take part in a residential short-term drug and alcohol treatment center that only calls for a stay of 30 days or less. This option could be be a reasonable treatment possibility for individuals that have family or work obligations, and simply need a short but somewhat intensive course of rehab. Moreover, persons with a very brief background of alcohol and drug addiction may possibly find that this may be a valid selection while an individual with a more extensive and serious history of abuse and addiction may very definitely require a more extensive time in treatment. If an individual does have a more serious history of substance abuse and chooses a residential short-term rehab program of as little as a month, it is often required that they follow up this treatment with standard follow-up care or move to an aftercare program so that their sobriety can be monitored and so can receive the support needed in their rehabilitation process as often as possible.
